Research in the Crease lab uses freshwater crustaceans in the genus Daphnia as a model organism to study evolution of the ribosomal (r)DNA multigene family, and of the DNA transposon, Pokey, which inserts in a specific region of the Daphnia rDNA repeat as well as other genomic locations. Current projects involve comparing rates of evolution in ribosomal proteins that bind to conserved and variable regions of rRNA genes, determining the impact of breeding system (cyclic or obligate parthenogenesis) on the evolution of rDNA and Pokey transposons, determining the relationship between rDNA copy number and Pokey distribution, and measuring rates of Pokey transposition inside and outside of rDNA.

Dr. Heyland's laboratory uses novel functional genomics approaches to study the endocrine and neuroendocrine systems of aquatic invertebrates. Specifically he investigates the function and evolution of hormonal and neurotransmitter signaling systems in the regulation of development and metamorphosis. His research includes evolutionary development studies of marine invertebrate metamorphosis, eco-toxicogenomic approached to understand endocrine disruption in aquatic ecosystems and water remediation technologies. These projects are integrated with several national and international collaborations ranging form basic scientific work to industry partnerships.

We are interested in characterizing the mechanisms of pathogenesis, adaptation, and survival in fungal and bacterial microbes from a systems biology perspective through mass spectrometry-based quantitative proteomics. Specifically, research in the lab centres around the following areas:
1) Systems biology to elucidate microbial proteome dynamics and interactions;
2) Mechanistic characterization of pathogenic proteins; and
3) Mass spectrometry-based proteomics for drug discovery and repurposing.

The Cox lab aims to gain a better understanding of the molecular underpinnings of resistance mechanisms. Specifically, we study bacterial efflux systems, which will provide insight into their physiological functions and origins and will also support future drug discovery efforts and antibiotic stewardship. In addition, recognizing the need for innovation in the search for new antibacterial agents, we are exploring novel approaches to control bacterial infections by investigating the inhibition of bacterial adhesion to host cells.

The main goal of our research program is to understand how the intrinsically disordered late embryogenesis abundant (LEA) proteins are able to protect plants from damage caused by cold, drought and high salinity. Our main focus has been on dehydrins, a group of abiotic stress response proteins that have been shown to protect plants from damage caused by drought and cold. Dehydrins are interesting in that they are composed of a variable number of conserved motifs that appear to have roles in protection of proteins, membranes and DNA from abiotic damage, as well as roles in localization.
